RUNNING-GEAR FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 223,515, dated January 13, 1880.

Application filed June 26, 1879.

To all whom it may concern Be it known that I, DAVID WV. INMAN, of Stelvideo, in the county of Darke and State of Ohio, have invented certain new and useful Improvements in Running-Gear for Vehicles and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an improvement in the running-gear of that class of wagons which do not employ the fifth wheel, but instead have a coupling-pole pivoted by the king-bolt between the front axle and bolster, and sliding on the brace-bar which connects the rear ends of the hounds.

In this class of vehicles the greatest amount of wear and friction occurs at the points of contact between the coupling-pole and its slidin g bar, and this friction soon wears away the parts, and eitherdestroys the coupling-pole or the slide-bar, or both.

My invention consists in pivoting a rollerin a longitudinally slot-ted metal plate, which plate is secured to the under side of the coupling-pole over a recess made to accommodate the roller, which lies just over and rests upon the slide-bar.

The novelty consists in the construction, combination, and arrangement of the parts, as

. will he herewith set forth and specifically as represented, with the forward end of the coupling-pole pivoted between 'the axle and bolster by the king-bolt a.

The under side of the coupling-pole, just over and somewhat on each side of the slidebar D, is recessed longitudinally. Over this recess. is fastened a metal hearing-plate, I), having a longitudinal slot through it, as seen in Fig. l.

In suitable bearings 0, attached to or forming a part of the plate I), at each end of the slot, is jou-rna-led a friction-roller, d, as'represented. This roller lies in the before-mentioned recess in the pole, but projects through the slot inthe plate sufficiently to bear upon the slide-bar l) and prevent the contact of the coupling-pole with said slide-bar.

The roller is sufficiently long to always hear and travel upon the slide bar, whether the wagon is in a straight line or turned around to its farthest limit either way.

By this simple construction and application of the roller all wear of the coupling-pole and slide-bar is prevented and the friction is reduced to a minimum.

Having thus fully described my invention, I claim and desire to secure by Letters Patent The combination, with a coupling-pole and slide-bar, of a friction roller, (1, pivoted in bearings c at each end of the longitudinal slot formed in the metal plate I), which plate is secured to the under side of the couplingpole,

the whole constructed and united substantially 7 5
